I think a hotel is the better option. You can always try to protect the people there by putting a sign up to alert authorities too.
Yes, I expect someone from your family would still be called to identify you but, they would be going in knowing that's what they were about to do. They wouldn't just be walking into the living room or wherever you would plan to do it at home. I doubt- following that they would be able to dissasociate that room with that sight.
The only thing I can think of where it may be of more comfort would be a sense that they wish they could have been there right at the end. Sometimes, you do get the sense that loved ones want to be able to do stuff for their family members- even after death. Maybe it helps with closure or something. But, you think how families will go to great lengths to take care of the remains.
Still, it would be obvious that you had chosen to go to a hotel to spare them the trauma so, I would have thought they'd be grateful for that.
